In the case of no tillage radical changes are to be noticed in relationship to the conditions of conventional technology. No-till technology doesn’t require any processing of the soil on the whole working width but only on the narrow range; depth is reduced (max.10.cm) and crop residues remain on the surface. In these circumstances the entire aero-hydric soil system is different from conventional technology and soil characteristics (structure, density, permeability) are also different.The no-till machines can be equipped with chisel coulters or disc type furrow. Each of these options has advantages and disadvantages in terms of functionality and technology. This paper proposes a critical comparative analysis between two sections of the no-till machine equipped with specific coulter chisel and clutch disc type to identify the best solution for seedbed preparation and ensure maximum contact of the seeds with the surrounding soil.
